| Brief Description | In this module, students investigate distance-time graphs. They first create a graph of their own journey from home to school. Then they use real-world experiments and the Desmos applet "walking graphs digitally". Understanding of graphs is enhanced by directly linking a physical experience (motion) to visually perceivable information in the graph (slope, position, direction). The "walking a graph" situation describes the relationship between the distance to a fixed point/sensor and the time it takes to complete a movement. Students experience this situation through walking to and form an ultrasonic sensor in the classroom and in a digital environment using Desmos. The focus of this module is on developing and promoting a qualitative understanding of functional relationships. The module engages students with the relationship between distance and time, exploring the graphical representation and the rate of change in distance-time scenarios. |

| Learning Goals |
- Students learn to identify and name the quantities that vary in given scenarios
- Students learn how to express and coordinate the co-variation of two quantities
- Students learn to identify and represent (verbally, symbolically, and graphically) the correspondence relation between two quantities
- Students learn to create and interpret graphs of functional relations
- Students learn to generalize (verbally and symbolically) the correspondence relation between two quantities
- Students learn to use functional expressions to model real-life scenarios
